Application September 12, 1957, Serial No. 683,533

Claims. (CI. 33-56) This invention relates generally to an improved sight and more particularly to an improved sight and more particularly to an improved sight suitable for use on rifles and other firearms and weapons.

It is an object of this invention to provide an improved adjustable gunsight.

Another object of this invention is to provide an adjustable gunsight which can be attached to the stock or barrel of a firearm and which has a relatively free field of view.

An important object of this invention is to provide a gunsight which provides a wide field of view and maintains a constant relationship between the eye of the shooter and the gunsight irrespective of adjustments made in the elevation and windage corrections set on the gunsight.

An additional object is to provide a relatively simple and economical gunsight which is easily manufactured and installed on a firearm and which will provide a rugged construction exhibiting considerable durability in use without the possibility of becoming out of adjustment due to hard use.

These and other objects will become apparent from the following detailed description of the invention taken in conjunction with the accompanying drawing in which:

Fig. 1 shows a side elevational view of a rifle with the gunsight of the present invention mounted on the stock thereof;

Fig. 2 shows a plan view of the gunsight showing the adjustment scales and indices;

Fig. 3 is an end view of the gunsight from the muzzle end of the firearm showing the sighting notch; and

Fig. 4 is a bottom view of the gunsight showing the elevation adjustment slots.

Referring now to the drawings, wherein like parts are designated by like numerals throughout the various views, in Fig. 1 a firearm comprising a barrel 11 fitted to a stock 12 has mounted thereon the improved sight provided by the invention. The firearm comprising a barrel 11 and stock 12 may be of any particular configuration and for the purposes of illustration a lever action rifle is shown. It is to be understood, however, that the present sight is well adapted for installation on any type of weapon and is not to be considered as limited to the particular arrangement shown.

The sight includes a base member 14 which is shown as mounted to the stock 12 although in particular installations it can as readily be mounted on the barrel 11 of the firearm. The base 14 has an under surface 15 which generally conforms to the contour of the portion of the stock 12 upon which it is mounted for firmly supporting the elements of the sight. The base 14 has an upper surface 16 adapted to support the remaining portion of the sight as will hereafter appear. The base 14 has a rear portion 17 which may be of any desired thickness to provide the proper contour for the supporting surface 16 in any particular application. The forward end of the base 14 is formed with a vertical projection lug 21 having a curved upper surface 22 for supporting the forward portions of ice the sight. The base 14 has two longitudinal slots therein, best seen in Fig. 4, for the purpose of providing elevation adjustments in the setting of the sight by the forward or rearward movement of the base 14 as will hereafter appear.

Supported on the base 14 is the sight proper comprising a tubular member 25 having an inclined under surface 26 with a curved extension 27 formed integrally with a tapered plate 28 which is approximately coextensive with the base 14. The plate 28 is of generally the same contour as the upper surface 16 of the base 14 for sliding engagement therewith in adjustment of the elevation sets ting. The plate 28 has a forward transverse slot 31 and a rear hole 32 therein, best seen in Fig. 4, for receiving the mounting screws 33 and 34 which secure the sight in assembled relation to the firearm stock 12. The plate 28 is maintained in adjusted position by the rear mounting screw 34 and an upper dog 36 having a tapered end 37 bearing against the curved extension 27 of the tubular sight 25. The dog 36 has a countersunk bore 38 for accurate alignment of the bore 38 with the hole 31 upon assembly of the elements 14, 28 and 36 by the tightening of the forward mounting screw 33.

Referring now to Fig. 2 along one edge of the base 14 a scale 23 is provided which cooperates with a fixed index 29 on the plate 28 to provide an indication of the elevation adjustment of the sight. In like manner, an azimuth or windage adjustment is provided by the fixed index 39 in cooperation with a scale 24 on the plate 28 which moves angularly with respect to the pivot about the axis of the screw 34 upon a loosening of the forward screw 33 to permit the azimuth adjustment of the sight to the right or left.

In Fig. 3 an end on view of the sight shows the tubular member 25 with a cross wire 41 mounted therein in a horizontal position. The cross wire 41 has a centrally located notch 42 to act as the alignment notch for sighting the target. The tubular member 25 is inclined with respect to the mounting surface for the base 14 such that the sliding engagement between the member 25 and the lug 21 raises and lowers the forward end of the sight comprising the tubular member 25 to provide the elevation adjustment of the notch 42.

The adjustment features of the sight can be explained with respect to Fig. 4 which shows an underside view of the sight particularly the under surface 15 of the base 14 which has cut therein longitudinal slots 18 and 19 for the purpose of translating the base 14 axially along the stock 12. Upon loosening the screws 33 and 34 the axial movement of the base 14 may be effected. The slots 18 and 19 are accurately machined to cooperate with the body of the screws 33 and 34 to maintain the base 14 in predetermined alignment with respect to the barrel of the gun on stock 12. The alignment of the tubular member 25 is maintained by the mounting holes in the extension plate 28 being accurately machined to receive the rear screw 34 in a circular hole in the plate 28 while the forward screw 33 is received in a transverse slot 31. The slot 31 is cut into the plate 28 to provide for the azimuth adjustment of the sight as plate 28 is slid to the right or left about the pivot point formed by the axis of the screw 34.

While features of operation of the present sight are believed apparent from the foregoing description thereof, a brief description of operation will be included for the sake of completeness. When the sight of the present invention is to be mounted on a firearm an appropriate position for the sight is selected with regard to the field of view desired and the position of the sight with respect to the shooters eye and the operating mechanism of the weapon. When the position on the stock or barrel has been selected for locating the sight, two accurately positioned holes are drilled and tapped therein for mounting the sight by means of the mounting screws 33 and 34. The holes for screws 33 and 34 are in substantially exact alignment with the axial direction of the bore of the gun and provide upon the sight being assembled thereto a course alignment of the sight with respect to the direction the gun will shoot.

The sight is assembled by first placing the base 14 on the stock in alignment with the tapped holes to receive the screws 33 and 34 and the extension plate 28 is placed on the upper surface 16 of the base 14. On top of the plate 28 the dog 36 is positioned with its forward end bearing on the curved extension 27 and the screws 33 and 34 are inserted and lightly screwed into the tapped holes in the stock 12. The alignment of the sight in elevation is effected by axially moving the base 14 along the length of the gun within the limits of travel of the slots 18 and 19 to provide a variable elevation of the tubular member 25 as the upper surface 22 of the vertical extension 21 raises and lowers the tubular member 25 with respect to the supporting plate 28. The elevation adjustment can be noted and calibrated by means of the movable scale 23 and the fixed index 29. The azimuth or windage adjustment can be made by means of the transverse movement of the tubular member 25 with respect to the pivot point formed by the axis of the screw 34, the adjustment being accomplished within the limits of the transverse slot 31 moving with respect to the fixed position of the screw 33. Upon completion of the adjustments, the screws 33 and 34 are tightened to maintain the parts in fixed alignment at their predetermined adjusted positions. In final adjusted position the upper surface 22 of the extension 21 supports tubular member 25 against inadvertent downward deflections due to rough usage and in like manner the tapered end 37 of the dog 36 hearing down on the curved extension 27 prevents an upward movement of the tubular member 25 in the event it is caught on clothing, brush or other obstacles. For other adjustment in elevation the slight loosening of the screws 33 and 34 permits the base plate 14 to be translated along the axis of the weapon without changing the relative position of the shooters eye with respect to the tubular sight 25 thereby providing a fixed field of view irrespective of the elevation adjustment of the sight. Many modifications of the present invention will now be apparent to those skilled in the art in light of the present disclosure and are to be considered to be within the spirit and scope of the appended claims.
